What is a SIPP?
A Self-Invested Personal Pension — usually shortened to SIPP — is a type of defined contribution personal pension that can offer a wider range of investment choices and more control over how pension money is invested.
The basics
A SIPP is still a pension.
A SIPP is a defined contribution pension. Its eventual value depends on factors including how much is paid in, investment performance, charges and how benefits are taken later.
What distinguishes a SIPP is usually the level of investment choice and control available compared with a more traditional personal pension.
Investment choice
SIPPs can offer access to a wider range of investments.
Depending on the provider, a SIPP can allow investment in areas such as funds, company shares, government and corporate bonds, and some forms of commercial property.
Greater flexibility
You may have more control over asset selection and portfolio construction than under a standard personal pension.
More decisions
A wider investment range means more choices about diversification, risk, trading and ongoing management.
Investments can rise and fall in value. Holding a wider range of investments can be useful, but poor diversification or unsuitable investments can increase risk rather than reduce it.
Tax treatment
SIPPs receive pension tax treatment, subject to the normal rules.
Most personal pension contributions operate on a relief-at-source basis. The provider normally claims basic-rate tax relief from HMRC and eligible higher or additional-rate taxpayers may be able to claim further relief.
For 2026/27, the standard annual allowance is £60,000, although tapering and the Money Purchase Annual Allowance can reduce the amount available in some cases.
Annual allowance rules apply across your registered pension savings rather than giving each pension its own £60,000 allowance.
Costs
Compare the complete cost, not just the headline platform fee.
SIPP costs vary considerably. Depending on the provider and investments used, charges can include platform or administration fees, fund charges, dealing fees, adviser fees and other transaction or asset-specific costs.
MoneyHelper notes that lower-cost SIPPs often provide a narrower range of investments, while full SIPPs can provide more complex investment options and may cost more.
Moving existing pensions
Do not transfer an old pension simply because a SIPP looks more flexible.
Transferring an existing pension into a SIPP can mean giving up valuable benefits, guarantees or lower charges.
Guaranteed annuity rates, protected tax-free cash, protected pension ages, safeguarded benefits, exit penalties and employer contributions can all affect whether a transfer is appropriate.
The FCA also warns about arrangements involving international SIPPs where layers of charges or unsuitable offshore investments can create poor outcomes. Always understand the complete structure and cost before transferring.
Retirement
A SIPP can usually offer the same main retirement options as other defined contribution pensions.
Depending on the provider, this can include leaving money invested, taking tax-free cash, using flexi-access drawdown, buying an annuity or taking lump sums.
The normal minimum pension age is currently 55 for most people and is due to rise to 57 from 6 April 2028, subject to protected pension ages and limited exceptions.
Who might value a SIPP?
Someone who genuinely needs wider investment choice, wants more control or needs specific functionality not available in a simpler pension.
Who may not need one?
Someone whose existing pension already provides suitable investments, competitive charges and the retirement options they need.
Personal pension advice
Considering a SIPP or transferring an existing pension?
The useful comparison is not simply whether a SIPP offers more investments, but whether the additional flexibility improves your overall pension and retirement plan after costs and lost benefits are considered.
